Hence statement 3 and 5 are true from the equation given in question.

The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal.

Types of Equations:

  Linear Equation: More than one variable may be present in a linear equation. An equation is said to be linear if the maximum power of the variable is consistently 1.

 Quadratic Equation: This equation is of second order. At least one of the variables in a quadratic equation needs to be raised to exponent 2.

   Cubic Equation: A third-order equation is this one. At least one of the variables in cubic equations needs to be raised to exponent 3.

  Rational Equation: A fractional equation having a variable in the numerator, denominator, or both is referred to as a rational equation.

Number of cans used 1/10 part of room  = 1/2

No. of cans paints used 1 part = 1/2 / 1/10 = 5

∵ 1/2 can paint is used = 1/10

∴ 1 can paint used = (1/10)*2 = 1/5

∴ 5 cans  = 100%

3 cans used = (3/5)*100 = 60%

Answer:

9/40

Step-by-step explanation:

3/8=15/40

4/5=24/40

15/40 x 24/40=360/1600

360/1600=9/40

Step-by-step explanation:

The air plane is rising so the change in elevation is +1000 feet. The temp dropped and is -20 degrees fahrenheit.

1 degree per 50 ft

For every 1,000 feet that it climbs, the outside temperature drops 20 ... What is the rate of temperature change in degrees Fahrenheit per foot.

Hope I helped

Answer:

Step-by-step explanation:

part A=The airplane is rising, so the change in elevation is +1,000 feet. The temperature is dropping, so the change in temperature is -20 degrees Fahrenheit.

Part B= -20 degrees fehrenheit/1,000 feet

Part C=  -20 degrees fehrenheit/1,000 feet= -1 degrees fehrenheit/50 feet

The answer can also be written as -1 degrees fehrenheit/50  per foot.

Part D = The airplane is descending, so the change in elevation is -1,000 feet. The temperature is rising, so the change in temperature is +20 degrees Fahrenheit.

The rate of temperature change in degrees Fahrenheit per foot is 20/-1000

Part E= The answer can also be written as-1/-50

Part F= The rate in part E is equal to the rate in part C. It means that -1/50=1/-50=-1/-50

Answer:

$30

Step-by-step explanation:

Given that :

Amount earned for mowing = $45

Amount spent on music = $5

Amount earned for washing neighbor's car = $10

Amount saved = half or remaining amount

Amount of dollars Fred keeps =

Amount Fred keeps:

[(Amount earned - amount spent) / 2] + $10

[($45 - $5) / 2] +

($40 / 2) + $10

= $20 + $10

= $30

Answer:

it is because so you can evenly add it

Fail to reject H0

Step-by-step explanation:

Forecast for July 14 :

Assume there are 4 wwwks in each month :

January to June = ( 4 * 6 months) = 24 weeks in 6 months ;

July - July 14 = 2 weeks :

2 + 24 = 26 weeks

The model given :

Y = 450 + 10t

Y = 450 + 10(26)

Y = 450 + 260

Y = 710

2.)

Test is a 2 tail test :

Zstatistic = - 1.07

At 95% confidence = ±1.96

Zcritical = - 1.96

Hence,

Reject H0 if ;

Zstatistic < Zcritical

-1.07 > 1.96

Hence, fail to reject H0.

Step-by-step explanation:

Answer:

v < 9

Step-by-step explanation:

Since the value of the hat is less than 9, we will use a less than sign.

In the inequality, the less than sign has to be in front of 9.

So, put this together:

v < 9

The inequality is v < 9

Answer:

a) 7.78 months

b) 1116

Step-by-step explanation:

Given -

[tex]\frac{dP}{dt} = 0.4p-450[/tex]

Integrating the above equation with respect to time, we get -

[tex]\int\ \frac{dP}{0.4p-450} = \int\ dt\\[/tex]

let us define new variable x

[tex]x = 0.4p - 450 \\dx = 0.4 dy[/tex]

substituting these values in above integral equation, we get -

[tex]\frac{1}{0.4} \int\ \frac{dx}{x} = \int\ dt\\ln x = 0.4 t + C\\x = ce^{0.4t}[/tex]

[tex]P (t) = \frac{C}{0.4} e^{0.4t} +1125\\[/tex]

at t = 0, P (0) = 1075, using this condition, we get -

[tex]\frac{c}{0.4} = -50\\P(t) = 50 e^{0.4t} +1125 \\t = 7.78\\P(0) = 1125 - \frac{1125}{e^{4.8}} = 1116[/tex]

WITH WHAT THE SCREEN MAD BLURRY

Answer:

Step-by-step explanation:

Given that:

scores = 2, 3, 4, 4, 5, 5, 5, 6, 6, 7

Since the scores are already in ascending order; then the median which is the middle number will be:

median = (5th term + 6 term)/2

median = (5+5)/2

median = 10/2

meian = 5

b)

Use the cumulative percentage table

X     frequency    cumulative frequency     cumulative percentage

2         1                     1                                            10%

3         1                     2                                           20%

4        2                     4                                            40%

5        3                     7                                             70%

6        2                     9                                             90%

7        1                     10                                             100%

fraction = the no. required to reach 50%/ no. in that interval

= 1/3

Since we have a total of 4 boxes when we reach the value of 4.5
